What is the difference between EMS waves and mechanical waves? Select all that apply. * Mechanical wave require a medium to travel on. EMS waves do NOT require a medium to travel on. EMS waves do NOT require a medium to travel on but, they can use a medium to travel on.

EMS waves require no material medium to travel

Explanation:

Here, we want to consider the difference between mechanical waves and EMS waves

When we talk of EMS waves, we mean electromagnetic radiation waves .

Example of EMS waves include radio waves , x-rays etc

These kind of waves require no material medium to travel and this is the main difference they have with mechanical waves

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
